REVOLVING-LEAF TREATING-TABLE Application filed. January 26, 1911.

T 0 all whom 2'23 may concern:

Be it known that I, Crmsrnn V Aneniorrr, a citizen of the United States, residing at Danville, county of Vermilion, State of Illinois, have invented a certain new and useful Improvement in ltevolvingLeaf Treating-Tables, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its object to produce a treating table which will enable the physician, without the use of swings or other appliances, to loosen and to adjust the spines of patients in a simple and easy manner; produce several movements and combination of movements throughout the entire lumbar and dorsal regions of the spine; and to swing the spine, in the manner desired, of aged persons, fleshy individuals, cripples, rheumatics and others who cannot now be treated satisfactorily with the appliances available; all of the various manipulations being effected while the patients muscles are perfectly relaxed and without irritating the patients muscles, knees and other parts.

A further object of my invention is to produce a table of the kind specified which may be locked so as to form a rigid apparatus and thus serve as an ordinary treating table.

A further object of my invention is to provide a simple and effective means whereby a patient may brace himself and prevent himself from being pushed or rolled from the table during treatment.

The various features of novelty whereby my invention is characterized will hereinafter he pointed out with particularity in the claims; but, for a full understanding of my invention and of its object and advan tages, reference may be had to the following detailed description taken in connection with the accompanying drawings, wherein:

Figure 1, is a perspective view of my improved table with a patient lying thereon; Fig. 2, is a plan view of the table showing, in dotted lines several positions into which the movable partof the table may be turned; Fig. 3, is a bottom plan view of the table on a larger scale; Fig. 4, is a central longi- Specification of Letters Patent.

is an end view, looking toward the left in Fig. 4; Fig. 6, is a side view of a portion of one end of the table on a larger scale; Fig. 7, is a top plan. view of a part of the table, the upholstering being omitted; and Fig. 8, is a side elevation of an adjustable crupper strap which aids in keeping the patient on the table.

In accordance with my invention, I make a table having two leaves which are movable a-ngularly relative to each other and which may be locked together in one or more relative positions so as to present a rigid top. In the arrangement shown, A and B represent the two leaves, the member A extending almost the entire length of the supporting structure or frame C, and the member B overhanging the frame at one end. The member B is in the form of a leaf, which normally forms a'continuation of the stationary leaf and, when locked in this position, serves to produce a long, solid, substantially rectangular table which may be used as an ordinary treating table. I prefer so to arrange the parts that the swinging leaf may be turned in either direction from its normal position through a considerable angle as indicated in dotted lines in Fig. 2. The meeting ends of the two leaves are curved so that no gap is produced between them when the swinging leaf is moved. In the arrangement shown, the end of the swinging leaf is convex, while the corresponding end of the stationary leaf i concave. It is obvious that this arrange ment might, however, be reversed. The swinging leaf is mounted to turn about an axis approximately at the end of the supporting frame and coincident with the center of the segmental end of the leaf. There fore a considerable portion of the'swinging leaf overlies the supporting frame and causes the leaf to be solidly supported. In Fig. 2, the axis of rotation of the leaf is indicated at b. It will be seen that when a patient is lying upon the table and the swinging leaf is turned, the portion thereof which rests upon the supporting frame moves in the opposite direction from the portion which extends beyond the frame. Conse quently, a powerful twisting and bending effort is exerted upon a patient lying upon the table while the swinging portion is moved.

. The two leaves of the table are interlocked in any suitable manner in the vertical direction so thaiq the innenend of the swinging. leaf is held down and the leaf is prevented,

from tilting under the weight of the patient.

5 This interlocking of the two leavesmay beeffected in any suitable way. In the ar-..

While I have illustrated and described with particularity only a single preferred form of my invention, I do not desire to be limited to the details of construction so illustrated and described; but intend to cover all forms and arrangements which fall within the terms of the definitions of my in ention constituting the appended claims I claim:

1. A treating table having its top composed of a stationary leaf and a swinging leaf, said swinging leaf being pivoted so as to swing about an aXis extending transversely to the plane of the table top at a point considerably removed from both ends of the swinging leaf, and a rest carried upon the outer end of the swinging leaf.

A treating table comprising a rigid frame, a swinging leaf resting upon one end of the frame and projecting beyond the same, said swinging leaf being pivoted so as to be movable in a horizontal plane, and a stationary leaf secured upon said frame and forming with the other leaf the top of the table, the adjacent ends of said leaves leaf so as to form therewith the top of the leaf from tilting.

3. In a treating table, a rigid supporting frame, a leaf having one end resting upon the frame and the other end projecting beyond the same, a pivotal connection between the aforesaid leaf and the frame at a point between the ends of the leaf for permitting the leaf to swing in a horizontal plane, and a stationary leaf secured upon said frame adjacent to the inner end of the aforesaid leaf so as to form therewith the top of the table.

4. In a treating table, a rigid supporting frame, a leaf having one end resting upon the frame and the other end projecting be yond the same, a pivotal connection between the aforesaid leaf and the frame at a point between the ends of the leaf for permitting the leaf to swing in a horizontal plane, and a stationary leaf secured upon said frame adjacent to the inner end of the aforesaid leaf so as to form therewith the top of the table, said leaves being interlocked so as to prevent the swinging leaf from tilting.

5. In a treating table, a supporting frame, two leaves arranged end to end upon said frame, one of said leaves being pivoted between its ends so as to be capable of swinging in the plane of the leaves, the adjacent ends of said leaves being curved into arcs of circles having their center at the pivotal axis of the swinging leaf.

6. In a treating table, a supporting frame, two leaves arranged end to end upon said frame, one of said leaves being pivoted be tween its ends so as to be capable of swinging in the plane of the leaves, the adjacent ends of said leaves being curved into arcs of circles having their center at the pivotal axis of the swinging leaf, and means for locking the swinging leaf against movement.

7 A. treating table, a supporting frame, two leaves arranged end to end upon and supported by said frame, one of said leaves being pivoted at a point between its ends so as to be capable of swinging in the plane of the other leaf.

8. A treating table having an approximately rectangular top containing sections whose adjacent edges are curved about a common center in the arc of a circle having a diameter approximately equal to the width of the table, and a portion of the top extending on opposite sides of said center in a the direction of the length of the table and forming one end of the top and being movable around a vertical axis passing through said center.

In testimony whereof, I sign this specification in the presence of two witnesses.
